Serializable Instrument Input

[Unsuitable]

Hello,

Using this bit of code as an instrument input parameter for an indicator.

[NinjaScriptProperty]
[TypeConverter(typeof(NinjaTrader.Gui.Tools.Instrum entSelector))]
[Display(Name="Select Execution Instrument",GroupName = "Parameters", Order = 1)]
public NinjaTrader.Cbi.Instrument InstrumentInput
{ get; set; }

When trying to save the indicator to a chart I get the "There was an error reflecting type" error message. So it's an issue with XML. I double-checked the other properties and they are ok. The only one is this one... which is not a string. How does one convert to a string and back? I noticed there's a method called InstrumentDeserialized, not sure if that will help.

Thanks

Hello Unsuitable,

The Instrument object is not serializable, you would need to make a string property for the instrument name to be saved. This is just like a Brush or any other C# object that cannot be serialized.

You can make a serialize property like the following:

[XmlIgnore]
[TypeConverter(typeof(NinjaTrader.Gui.Tools.Instrum entSelector))]
[Display(Name="Select Instrument", GroupName = "Parameters", Order = 0)]
public Instrument InstrumentInput
{ get; set; }

[Browsable(false)]
public string InstrumentInputSerializable
{
get { return InstrumentInput.FullName; }
set { InstrumentInput = Instrument.GetInstrument(value); }
}

Please let me know if I may be of further assistance.

Hello Jesse,

Yup that's what I figured, wasn't quite sure how to convert it. It works. I noticed you removed the [NinjaScriptProperty] tag, is it required?

Thanks

Hello Unsuitable,

You would only need that for optimization properties or ones which should be included in the indicators constructor.
